SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed December 16, 1908. Serial No. 487,829.

To all whom it may concern" Be it known that I, JAMES ARXOLD Borrm, :1subject of the King of England, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Surgical instruments, of which the following is adescription.

My invention belongs to that class of de- .ices known as surgicalinstruments and relates particularly to an instrument aiilupted for usein ciroumcising operations and the like, am has for its object theproduction of a sim 1e, efficient, convenient and satisfac tory c eviceof the kind described and for the purposes set forth.

To this end my invention consists in the novel construction,arrangement, and eomhination of parts herein shown and described, andmore particularly pointed out in the claims.

In the drawings wherein like reference characters indicate like orcorresponding parts; Figure 1 is a View in elevation ofany preferredform of instrument and the dhsc therefor. Fi 2 is a \lU-W in elevation:of the same ready for a mlication. Fig. 3 is a View in elevation of thesame in operative position. Fig. 4 is a side elevation of the preferredform of instrument, and Fig. 5 is anend elevation of the case, theinstrir mcnt removed. i

The instrun'ient is designed to be used by surgeons in performing theoperation known as circumcision, it being adapted to retain the skin tohe removed in a position where the operation may he easily and perfcctly made by one surgeon without assistv ance.

taining the skin in a distended position as shown in Fig. 3 and morefully explained hcrciuafter. The instrument shown is made-of wire andpreferably bent as at 3 to form the two resilient arms 1 and 2,

which normally tend to sprin away from each other at, the free ends. hefree ends may be arranged in any suitable manner to retain the skin inthe desired position. In the instrument shown the free ends of the armsare bent to form hooks ek-Awhieh have their points sharpened so that theflesh may he engaged. The arms a 9. also prefer ihly hent between theends as at 5-4) to forn'i enlarged portions or loops, througl'i whichthe oprrators fingers may he passed. or a firm gri p on the inslrnn'ientbe obtained. I also preferably provide a suitable case 6, in which theinstrument may be positioned, and the points he thereby protected. Asshown the instrument is retained in the case by the lugs or extensions7-7 and tL-S thereon. the points 4--4 heingr protected by the lugs orex'ta-nsious 9 9 on the case.

Tn the circmncising operation, the foreskin 10 is drawn up substantiallyas shown in Fig. i. and the instrument applied, the parts to be operatedon having proferal'ily been previously lrealed in the usual or anysuitable way to deaden or kill any pain.

The books 4---4 having engaged the flash the resiliency of the arms land2 tends to draw the skin substantially as shown in Fig. fl. Tho surgeonthou lakes the inslrunienl in on hand, preferably with a linger throughthe. loops to give control of the in strmncut and with his scissors orknife in the other hand performs the cireui'ncising' operation forcfiamplo as at 11, In this nay a perfct't operati n may he performed bya surgeon without assistance.

Having thus described my invention, it is obvious that variousiiunmtorial changes may he made in the form or construction shown anddescribed, or that it may housed \rhercrcr applicable. hence I do notWish to be understood as limiting myself to the exact form shown anddescribed.

\Vhat I claim as new and desire to secure by lit-Hers Patent is surgicalinstrument of the character dcst-rilwd comprising a pair of arms, aresilient loop connecting said arms, a pointed, out-turned and unwardlvdirected hook at tho xt'rvmity of each of said arms, loops signed myname in the presence of two subfurn'nng finger gnps, said loops belngHfl'lblllg witnesses. formed in smd arms and lymg at mght w 1 1 anglesto the connecting loop, and said arms JAMES AINOLD BOB F1 projectingfrom diametrically opposite por- Witnesses: tions of said loops.
